Well, it was when HL2 was delayed. They were running out of interviews/news/etc stuff so they started to add PS/XBOX/Nintendo news rumours etc to fill up show time -> they were popular, especially PC Game Reviews -> added more and more (like movie reviews, ALT+CTRL+Rock, Wacky news..) and they changed their name to Gameshout.
But then came Lost Colony (MMOFPS game from Red Planet LLC, company behind Gameshout). Though i don't know why Gameshout was closed down anyway. Maybe Andy Hodges (guy that is owner? of Red Planet LLC) didnt have resources to run radio station and develop that new game at the same time. if anyone knows let me know.
I think Gameshout was (and still would be) the best Gaming Radio Station. Andy Hodges (you love him or you hate him), Capt. Maverick, SexyJosh, Ghost Freeman
